invention"relai'v'es to incinerator and more particularly to an incinerator adaptedifor installation in parksnesorts and pieniccgroun'ds orathe likeiifor the disposal 'of garbage and trash.

' The primary obje'c't'pf 'thisinvention to dispose o'f'trash and garbage without perceptible fismolceior odor, witha.r'ninimu-m consumption of -mel," and withina minimum of time.

:r-nnother important :objectrof this invention is toi tprovide arcompactioil burning-gravity .fed inninerator thatwillinexpensively burn to a minute ash any type of garbage and trash by consuming thegarba'ge or trashatahigh'rate of disintegration.

ilno'tlmar ob ie'ct ofithis invention isito provide anrzincinerator irom which the ashes'may v be easily removed, whichmay :be' easily :cleaned, and which may be easily-erected and dismantled.

:Ehese and ancillary "objects and other struc total :features bf' merit are attained by this invention, sa preferred embodiment of is set forth in the following description :andillustrated ins'thezaccompanyin'g drawings, wherein;

.lfiig'iire '1 is :a front elevational view of an incinerator, constructed in accordance with "the principles of this invention, 'and showingltnelhood in its normal "position seated on the "top bi the hodyand inamopeh dotted position;

Figure 3 is a vertical sectional view taken substanti'ally on the plane of line 3-3 of Figure 4, looking in the direction of the arrows;

Figure 4 is a transverse sectional view, taken substantially-on line 3-4 o'f ';Figure"3,- looking in the direction of the arrows-and illustrating tho grate construction; I

F'igure S is a transverse sectional view takenon l'inef-5-5 of Figure 3, and looking in the direct-ion or the'arrows, and, g Figure 6 is an enlarged vertical sectional view taken substantially on line 66 of Figure l, and looking in the direction of the arrows, to illustrate the grate structure.

Referring now more particularly to the drawings, this invention generally designated by the character reference l comprises a vertically disposed cylindrical metal body l2, which is provided with horizontally disposed alternating ribs l4 and grooves IS.

A conical shaped hood I8 is hingedly secured as at 20 to the upper edge of the body and is formed at its lower end with an annular flange 22, adapted to engage the outer surface of the upper edge of the body and retain the hood thereon.

The hood terminates at its minor end or upper end in an upwardly extending cylindrical outer nue tram the upp'er endof which'ex tendsin a transverse plane astackca'p 26-. Theeape fi 'is iormedsintegrall y withthe stack or outer iiiie' 'Z l and the opposing ends 28 and 30 thereof-extend beyond "the :sides of the stack. The openings termed thereby are covered with a fine mesh screen 32, so that screen outlets are previde'd'ior theproducts of combustion but burning pieces of garbage or trash rare 4:aptivated within ineinerator.

Means is provided toraswingin'g thenood from its seated position outwardly from the-jbody and for retaining the same in a horizontal detached position,as illustrated in Figure 1. The means includes an angularhandle 3-4 which is pivotally secured at 316 to a .lateiallyextending perforated ear 38 formed integrally on the outer-surface of the side wall of'the hood. Ihe hood can be held in the desired open position by placing the lower unattached end 40 ofthe' handle in the selected groove 16 of the body, whereby garbage or trash maybe inserted through the open-top of the body, without' theneces'sity of holding the hood in an open osition.

The lower portion of the body terms a firebox '42,a portionof. the lower wall oi the body being formedwith- 'an air inlet opening '34 and the adjacent portion o'f-the-body being bent outwardly-to form parallel wings "45 and i'B. 'The wings are oonnected'at their on'te-r lower edges by an angle A cylindrical housing 52 is vertically disposed centrally within the firebox and constitutes a bnrnen which includes a helical column "Bi-disposed within the housing and terminating at the upper end thereof in a four-way jet 56. A-tube SBisiormed integrally wit-hthe lower end of the burner coil and is adapted for association with a fuel connection in-a conventional manner.

A slidingor vibrating grate '60 is horizontally disposed above the upper end or" the housing and is vertically spaced therefrom, the grate being mounted on a pair of parallel rails 82 and 64. An inverted conical shaped basket-type oscillating grate 66 is disposed above the sliding grate and the major or upper end 68 thereof is provided with laterally extending circumferentially spaced trunnions or hangers 10 which are adapted to rest slidably 0n angle members or brackets 12 fastened as at 14 to the side walls of the body. Thus, the basket grate is suspended in an inverted position for limited oscillation above the sliding grate by means of the complementary trunnions and flanges or angle members carried by the side walls of the body.

An actuating rod 16 is secured to the sliding grate and terminates in a laterally extending depending end 18 which is received within a lug 80 formed laterally on a vertically disposed lever or handle 82. The handle 82 is pivoted as at 84 to the vertical portion of the angle iron 58. The lever or handle is received within the bifurcated end 86 of a handle extension 88 for a band 90, the latter being secured around the lower minor end of the basket grate.

An elongated tubular inner flue 92 is centrally disposed within the body and has its lower end positioned within the basket grate. The inner flue is horizontally corrugatedand formed with a plurality of perforations 95. The flue is supported by a suspension rod 94 which is transversely disposed through the opposing sides of the body. A damper 96 is pivotally secured as at 98 to the upper end of the flue and is adapted to seat on the upper end of the flue and functions as a cap to force the flame outwardly through the perforations 95 of the flue. The damper is controlled by a link rod I and a bell crank I02 pivotally secured as at [M to the link rod and fixed on the suspension bar 94. Thus, rotation of the extending end of the suspension bar rotates the crank and closes the damper in a similar manner, the rotative movement of the crank is translated into an upward, sliding movement of the link rod and an outward swinging movement of the damper for moving the same into an extended open position.

In operation, it can be seen that the hood can be swung open by means of the handle and held thereby in an open position, so that garbage and trash can be deposited into the body, the garbage or trash gravitating toward and into the basket grate. As the material moves downwardly, it is dried and burned in its fall by means of flames passing through the perforations, in the flue 92. it can be appreciated that with the hood closed, the articles of combustion will be allowed to pass through the screened openings. The corrugations formed in the body and flue will permit the flames from the burner to pass along the corrugations and evenly heat the body and flue, so that the refuse will be dried upon contacting the flue and body. It can be seen that the refuse Will be sifted and completely burned by vibrating or reciprocating the sliding grate 66 and oscillating the basket grate 56, so that a minute and flne ash will be deposited in the firebox, from which it can be easily removed through the opening therein. The lever or handle 82 thus constitutes common means for actuating both of the grates. By swinging the handle 82 laterally on its pivotal mounting 84, the upper grate 66 will be oscillated on the brackets '52 through the elements 86, 88, st, etc. There is enough resiliency and play in the mem- 4 bers 76, 18, 80, etc., to permit this. Then, by actuating the handle 82 longitudinally in the yoke 36, the lower grate will be vibrated or reciprocated longitudinally on the rails 52 and 6 t through the rod 16. There is suflicient looseness or play in the pivotal mounting 84 of the handle 82 to permit such actuation of said handle.

However, while one embodiment of this invention has been shown, it is to be understood that certain other embodiments can be carried out,

as coming within the spirit and scope of the invention, what is upper portion of the casing, a perforated, vertical flue, open at its ends, journaled on said shaft and depending therefrom in the casing in spaced, concentric relation thereto and communicating therewith adjacent the grate and the outlet at its lower and upper ends respectively,

a damper hingedly mounted on the flue for closing the upper end thereof, and means operatively connecting the damper to the shaft for actuation thereby.

2. An incinerator comprising a vetrical cylindrical casing having an air inlet in its lower portion and an outlet in its upper portion for the products of combustion, a grate in said lower portion of the casing, a horizontal, manually operable shaft journaled diametrically in an upper portion of the casing, a perforated, vertical flue, open at its ends, journaled on said shaft and depending therefrom in the casing in spaced, concentric relation thereto and communicating therewith adjacent the grate and the outlet atv its lower and upper ends respectively, a damper hingedly mounted on the flue for closing the upper end thereof, and means operatively connecting the damper to the shaft for actuation thereby, said means comprising an arm fixed on the shaft, and a link pivotally connected to said arm and to the damper.
